Vehicle Cannot Be Started From D1

SYMPTOM: 

Vehicle cannot be started from D1 on Cruise test - Part 1. 

1. CHECK SYMPTOM 

   Is "Vehicle Does Not Creep Backward in R Position" OK?

   Yes or No

   • Yes: GO TO 2.
   • No: Go to "VEHICLE DOES NOT CREEP BACKWARD IN R POSITION ".
2. CHECK SELF-DIAGNOSTIC RESULTS 

   Does self-diagnosis show damage to vehicle speed sensor. A/T (revolution sensor), overrun clutch solenoid valve, torque converter clutch solenoid valve, shift solenoid valve A, B or vehicle speed sensor MTR after cruise test?

   Yes or No

   • Yes: Check damaged circuit. Refer to "DTC P0720 VEHICLE SPEED SENSOR A/T (REVOLUTION SENSOR) ", "DTC P1760 OVERRUN CLUTCH SOLENOID VALVE ", "DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE ", "DTC P0750 SHIFT SOLENOID VALVE A ", "DTC P0755 SHIFT SOLENOID VALVE B " or "DTC VEHICLE SPEED SENSOR MTR ".
   • No: GO TO 3.
3. CHECK ACCELERATOR PEDAL POSITION (APP) SENSOR 

   Check accelerator pedal position (APP) sensor. Refer to "DTC P1705 THROTTLE POSITION SENSOR [ACCELERATOR PEDAL POSITION (APP) SENSOR] ".

   OK or NG

   • OK: GO TO 6.
   • NG: GO TO 5.
5. DETECT MALFUNCTIONING ITEM 
   1. Remove control valve assembly. Refer to "CONTROL VALVE ASSEMBLY AND ACCUMULATORS ".
   2. Check the following items:
      • Shift valve A
      • Shift valve B
      • Shift solenoid valve A
      • Shift solenoid valve B
      • Pilot valve
      • Pilot filter
   3. Disassemble A/T.
   4. Check the following items:
      • Reverse clutch assembly
      • Low & reverse brake assembly
      • High clutch assembly
      • Forward clutch assembly
      • Forward one-way clutch

   OK or NG

   • OK: GO TO 7.
   • NG: GO TO 5.
7. DETECT MALFUNCTIONING ITEM 
   1. Remove control valve assembly. Refer to "CONTROL VALVE ASSEMBLY AND ACCUMULATORS ".
   2. Check the following items:
      • Shift valve A
      • Shift valve B
      • Shift solenoid valve A
      • Shift solenoid valve B
      • Pilot valve
      • Pilot filter

   OK or NG

   • OK: GO TO 8.
   • NG: Repair or replace damage parts.
8. CHECK SYMPTOM 

   Check again.

   OK or NG

   • OK: INSPECTION END 
   • NG: GO TO 9.
9. CHECK TCM INSPECTION 
   1. Perform TCM input/output signal inspection. Refer to "TCM TERMINALS AND REFERENCE VALUE ".
   2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

   OK or NG

   • OK: INSPECTION END
